OK I installed LDC pre-built on MinGW for Windows on Windows and then Installed MinGW for Windows but when I run ldc2 it tells me libgcc_s_dw2-1.dll is missing.

Is this problem soluble by any means other than destruction of Windows?

You need to set PATH in environment variables to the directory where shared libaries of MinGW are present...

Hummm… I thought I had since all the DLLs are in the bin directory and you need that in your PATH. Ah, I installed MinGW that has libgcc_s_seh-1.dll not libgcc_s_dw2-1.dll.

Of course having a gcc and g++ in my path ruins all my SCons experiments since the whole point was not to have them in the path, just ldc2. Ho hum.

SEH was patented, so llvm doesn't support it.

I installed the other MinGW option and it provides libgcc_s_sjlj-1.dll which is not helping me actually run ldc2 on Windows :-(

Looks like mingw supports 3 types of exception handling. LDC usually tightly coupled with mingw version, you shouldn't try it blindly, but follow installation instructions instead.

That has changed.

Seriously, if they're worried about infringing a software patent, they have no business writing any code at all. Avoiding things covered by patents *and* writing code that actually does anything useful is NOT REALISTICALLY POSSIBLE. The SEH patent is just a red herring here.

It is mentioned both the in README coming with the Windows packages and the on wiki [1] that you need a Dwarf 2 EH package (-dw2) of MinGW-w64 for LDC to work.

How can we make this more clear?

Has it? SEH on Win64 is something entirely different from the original (x86) SEH design, and not covered by said patent.
